Opis:
Activity of soil dehydrogenase (DHA) was measured in the mineral soil in a forest stand of 15 to 16-year-old Scots pine (Pinus sylvestris L.) from geographically diverse populations, as an indicator of biological activity of soil microorganisms, in a provenance experiment in Poland. The pine populations originated from six European countries (Sweden, Russia, Latvia, Poland, Germany, France) and differed widely in aboveground biomass and productivity. Soil DHA during two growing seasons showed pronounced seasonal variability, which was significantly related to the fine root concentration of nonstructural carbohydrates. Higher DHA was found in soil under canopies of the central and southern European populations than in those from more northern parts of the Scots pine range. Significant positive correlation between soil DHA and aboveground tree biomass suggest that these patterns most likely resulted from differences in carbon dynamics and productivity among populations.

Opis:
The study presents the results of the analysis of development stages of Luronium natans (L.) Raf. depending on water conditions (pH, light, total nitrogen, total phosphorus, organic carbon) in 21 populations in north-western Poland. The fractions of seedlings, juvenile, mature and generative stems, as well as the course of phenological phenomena were determined. Seedlings are sparse and can be found from May to July. Most of them occur in waters ranging from slightly acid to neutral (pH 6.0-7.0) with TP concentrations of 10-20 µg dm-3, TN concentrations < 1.0 mg dm-3 and DOC concentrations of 3.5-5.0 mg dm-3, on a mineral (5-10% OC) and fairly well lit (31-40% PAR) substrate. The generative phase lasts from May to October. The flowering period is between August and mid-September. Only 35.2±9.4% of flowering stems produce fruits. The plant flowers abundantly in waters with total nitrogen concentrations > 1.2 mg dm-3, that is above the level of TN concentrations most favourable to seedlings and both juvenile and mature individuals. TP and DOC concentrations, and light intensity (PAR) do not influence the size of the generative stems fraction in populations. However, sediment structure is of importance in this respect: about 62.9% of stems flower and fruit on a mineral substrate (< 1% OC), whereas only 17.4% do so on an organic one. The results of this study may be useful in the conservation of this endangered European endemic species.

Opis:
The study on the distribution and abundance of beaver families in the Augustowska Primeval Forest was conducted in the years 2000 -2003. It embraced all seven Forest Inspectorates administering the Forest. The study consisted in the penetration of banks along watercourses, lakes and drainage ditches. Lodges, bank dens, dams and the length of the banks colonized by beaver families were plotted on maps. Habitat types contained within the territories of individual beaver families were established on the basis of the maps obtained from Forest Inspectorates. The percentage of bank utilisation by beavers in various types of water bodies was determined. The number of beaver lodges and bank dens, as well as their number per family were established. Also, habitat preferences of beavers in individual water bodies were verified. The presented study has the form of a report which can be used for further monitoring of beaver populations in the Augustowska Primeval Forest.
W latach 2000–2003 prowadzono badania nad populacją bobrów w Puszczy Augustowskiej. Ogółem w 7 nadleśnictwach stwierdzono 290 rodzin (Tab. 1). Analizowano 5 typów akwenów: rzeka Czarna Hańcza, Kanał Augustowski, inne rzeki, jeziora i rowy melioracyjne. Największe zagęszczenie bobrów w Puszczy stwierdzono przy ciekach i jeziorach. Z ogólnej liczby 290 rodzin ujawniono 35 rodzin na rowach melioracyjnych. W każdym typie akwenów analizą objęto: położenie żeremi, nor, długość areałów rodzin i wybiorczość siedlisk. Określono w % wykorzystanie brzegów akwenów (Tab. 2) oraz długość brzegu zajętego przez jedną rodzinę (Tab. 3), wybiorczość siedlisk przez bobry (Tab. 4, 5, 6). Ponadto określono liczbę żeremi, nor i gniazd łącznie w rożnych akwenach w poszczególnych nadleśnictwach (Tab. 7), a także ich liczbę przypadającą na jedną rodzinę (Tab. 8). Dane dotyczące rodzin na rowach melioracyjnych przedstawiono w tabelach 9– 11.

Opis:
To assess the inter- and intrapopulation genetic variation in the filial generation (F1) of alder (Alnus glutinosa (L.) Gaertn.), 11 naturally regenerated populations were analysed. Their parental populations (P), represent the whole Polish territory and belong to three phytosociological associations with alder: typical alder swamp forest Carici elongatae-Alnetum (Ce-A); alder riparian forest Circaeo-Alnetum (C-A); and ash-elm riparian forest Fraxino-Ulmetum (F-U). F1 populations are grown in a common-garden experiment (provenance trial). Genotyping of individual trees has been carried out by analysis in a bud tissue allele frequency in the 21 isozyme putative loci of 10 enzymes. Differences between populations in respect to the level of genetic diversity were not high. Genetic diversity measured as the number of effective alleles per locus was the highest (Ne = 1.65) in population Wińsko originating from F-U (where also the inbreeding coefficient was the highest, F = 0.429), and the lowest (Ne = 1.48) in population Sławki from Ce-A. In all investigated populations, observed heterozygosity (Ho = 20%) was lower than expected from H-W equilibrium (He = 29%). The highest genetic variation expressed as percentage of polymorphic loci (77.3%) was observed in the offspring populations from Ce-A, and the smallest (69.9%) in the populations originating from F-U. It seems that the low genetic differentiation between populations is probably connected with long-distance seed dispersal via river systems. Alder seed can be transported over long distances thanks to periodical flooding. There is some gene flow between alder populations, with about 2.5 immigrants successfully entering a population per generation (Nm = 2.55). The level of population subdivision within A. glutinosa was low (Fst = 0.089). There was no significant genetic differentiation between populations from different phytosociological associations. Mantel test exhibited no significant correlation (r = 0.077) between genetic and geographic distance. In the dendrogram constructed according to Nei (1972) on the basis of interpopulation genetic distances, many small groups can be observed.

Opis:
Seasonal changes in the morphometric and physiological parameters of the cockle Cerastoderma glaucum (Bivalvia) from the Baltic Sea (GD), the North Sea (LV), and the Mediterranean Sea (BL) were investigated. The cockles from GD were much smaller than those from other populations due to osmotic stress. The female to male ratios did not differ significantly from 1 : 1. The northern populations (GD, LV) had a monocyclic reproductive pattern, whereas the southern population (BL) seemed to reproduce throughout the year. Seasonal changes in the contents of biochemical components appeared to be correlated with changes in trophic conditions and the reproductive cycle. Protein content was the highest in spring for all the populations. The highest lipid contents and lowest carbohydrate contents were noted in GD and BL in spring, while no marked differences were noted among seasons in LV (probably because the data from both sexes were pooled). Respiration rates in GD were the highest among the populations, which could have been due to osmotic stress. High metabolic rates expressed by high respiration rates in GD and LV in spring and autumn could have resulted from gamete development (in spring) and phytoplankton blooms (in spring and autumn).

Opis:
Swine influenza virus (SIV) of H1N1 and H3N2 subtypes are dominated in European pigs population. "Classical swine" H1N1 subtype was replaced by "avian-like" H1N1 subtype. It co-cir- culates with H3N2 reassortant possessing "avian" genes. In the present study, 41 SIV strains isolated from pigs with pneumonia, raised in 20 Polish farms, were identified and characterised. Since it was evidenced that isolates from the same geographic district and the same year of isolation are in 100% similar, 15 strains representing different district and different year of isolation were chosen to construct phylogenetic trees. Two genes, conservative matrix 1 (Ml) and the most variable, haemagglutynin (HA), were sequenced and subjected into phylogenetic analysis. The results of the analysis confirmed that "avian-like" swine H1N1 strains evolved faster than classical SIV strains. HA gene of these isolates have been derived from contemporary strains of "avian-like" SIV. In contrast, the Ml gene segment may have originated from avian influenza viruses. H3N2 strain is located in swine cluster, in the main prevalent European group of H3N2 isolates called A/Port Chalmers/l/73-like Eurasian swine H3N2 lineage, which has evolved separately from the human H3N2 virus lineage around 1973.

Opis:
Europa od kilkudziesięciu lat ulega demograficznemu starzeniu. W perspektywie ten proces nasili się, co doprowadzi do zasadniczej zmiany proporcji między ludźmi młodymi i starymi. Liczba młodych, mających zastąpić osoby w wieku reprodukcyjnym (i zdolności do pracy) będzie maleć, natomiast liczba starych, wymagających wsparcia i opieki będzie rosnąć. Wzrastającym ze względu na wpływ czynnika demograficznego potrzebom w tej mierze będą towarzyszyć zmniejszające się zasoby demograficzne służące – w świetle obecnych standardów – do ich zaspokajania. Polska należy do krajów, w których ta zmiana będzie szczególnie drastyczna. Z jednego z najmłodszych obecnie wśród krajów Unii Europejskiej w 2060 roku stanie się najstarszym. Dowodzę, że ten proces – nazwany głównym wyzwaniem demograficznym Europy – jest nieuchronny i w najbliższych kilkudziesięciu latach nieodwracalny. Wbrew żywionym iluzjom, odpowiedzią na płynące z niego wyzwania społeczne i ekonomiczne nie są zmiany w sferze demograficznej, zwłaszcza wywoływane za pomocą polityk ludnościowych (w tym migracyjnej). Efektywnych rozwiązań trzeba oszukiwać w innych sferach.
For several decades now Europe has undergone population ageing. Within the coming half a century or so that process will be intensifi ed, which will result in a fundamental shift in the relationship between the youth and the elderly. Numbers of young people which are supposed to replace persons in reproductive (and working) age will be declining whereas numbers of old people, those who require support and care will be growing. In other words, an increasing demand related to those needs that will result from the ageing of population will be met by decreasing demographic resources, which – by present standards – serve the satisfaction of such demand. Poland belongs to countries where that change will be particularly drastic. By the year 2060 from one of the youngest populations in the European Union it will become the oldest one. I argue that this process – which I consider the principal demographic challenge Europe is facing – is unavoidable, and it will become irreversible within several decades. Despite illusions, a response to ensuing social and economic challenges cannot be found in the demographic change itself, especially the one to be accomplished by means of population policies (including migration policy). The effective solutions are to be sought in other spheres than the demographic one.

Opis:
To evaluate the geographic variability of Pinus sylvestris populations seven morphological traits of needles of pines from IUFRO 1982 provenance trial have been analyzed. The studied populations originated from northern (>55°N in Russia, Sweden and Latvia), central (55-47°N in Poland, Germany, Belgium, France, Slovakia) andsouthern (<47°N in Hungary, Bosnia, Montenegro andTurkey) European ranges of Scots pine. The analyzedprovenance trial experimental areas were locatedin Kórnik (western Poland) andin Supraśl (north-eastern Poland). The greatest variation was found in needle length and number of stomata rows on the flat and convex side of a needle, whereas number of stomata per 2mmof needle length on flat and convex side of a needle was stable, with minor interpopulational variation. Biometrical analyses revealed a significant population × location interaction anda geographical pattern in interpopulational differentiation in both experimental sites, with the northern andsouthern European Scots pine groups of provenancesdiffering significantly from the group of central origin. The results obtainedare compatible with previous results of studies on provenance variability of the Scots pine from IUFRO 1982. In the light of available data, the influence of the Balkan glacial refugia of Pinus sylvestris on a present genetic diversity of this species in Europe and the reconstruction of Scots pine migration routes after the last glacial period are discussed.

Opis:
We investigated the flowering probability and flower production in relation to plant size in a terrestrial orchid, Dactylorhiza majalis at 10 meadow sites in central and southwestern Poland. These sites differed in altitude (low, high) and management (presence or absence of mowing). At all sites, concentrations of nutrients in the soil were also measured. The probability of flowering increased significantly with the size of the plant in all populations, indicating that individuals do not flower until they reach a threshold size. Populations at high altitudes and the unmown sites had significantly lower threshold sizes for reproduction and showed sharp increase in flowering probability with plant size, compared to other populations. The threshold sizes for reproduction tended to decrease at sites rich in N and Mg and poor in P and S. Flower production was also size-dependent in all populations. Considerable between-site differences were found in the slope and the intercept of the regression between plant size and flower production. Flower production at some sites, at high altitudes, increased more steeply with plant size than at other sites. However, no pattern in size-dependent flower production was found relative to the measured environmental variables. Most of the size-dependent components of flowering probability were related to each other but not with the size-dependent flower production.

Opis:
Taxus baccata L. is a rare species threatenedwith extinction in Greece, as in other parts of Europe. This paper deals with the ecological status of the species in the area of NE Chalkidiki northern Greece, where the species appears in one of the greatest populations of the country. Site, standand yew population characteristics were studied in the area that species occupies. Eleven sample plots were marked, and on each plot, the height and diameter at breast height (DBH) were measured for all yew trees, as well as for all the individuals of the rest tree species, with diameter at breast height greater than 4 cm. Tree vitality of all trees was also estimated according to IUFRO classification. Yew radial growth was studied using tree-ring analysis. Tree natural regeneration was investigated within subplots of different dimensions and according to two height classes. Results showed that yew population occurs in stands dominated by beech, presenting a mean density of 301 trees per hectare, with a total population of 430 trees with DBH above 4 cm. It forms the secondary stand, and dominates in the stand understorey, accompanied with Fagus sylvatica and Ilex aquifolium, while it appears rarely in the overstorey. Yew tree vitality was foundto be quite high, and significantly higher than that of beech. Radial growth of the sampled trees follows a slow and constant annual increment gradually decreasing by tree age. Yew natural regeneration was foundto be relatively low, 1341.8 individuals (seedlings and saplings up to 1 m) per hectare. Management and in situ conservation of the species in the area should focus on species protection measures, andon specific silvicultural treatments for creating favourable conditions for species growth.

Opis:
The aim of this paper is to describe population ageing in member countries of the European Union and its dynamics in the period 1990-2030. Furthermore, we show chosen social consequences and challenges caused by demographic ageing. In the introduction, we present definition of the population ageing and describe measures used in the paper. The analytical part consists of three sections. The first one is about growth of older population (at the age of 65 and over, and 80 and over) in the years 1990-2030. The next one comprises an evaluation of progress in demographic change in the EU countries, which is based on chosen measures of population structure - aging index (population 65 and over to population 0-14), and potential support ratio (population 15-64 years to population 65 and over). In the analysis, we use also positional measures. The last part focuses on explaining regional differences in progress of demographic ageing of particular countries. The last section of the paper focuses on chosen socioeconomic consequences of ageing in the EU countries. One of them is an expected increase in number of disabled people. Another one is growth in the number of single person households of the elderly, who need familial and extra-familial care.

Opis:
Religious freedom has been always considered as a strong indicator democracy and institutional set up in a country. Ex- communist countries in their efforts to set up a state of law and foster democracy, particularly, are more sensible toward indicators such as religious freedom, tolerance and diversity considering them strong components of their social tissue necessary to set up a functional democracy. Their past legacy and history, are strong factors influencing their present and future. Analyzing the past, present and future of a country’s religiosity, religious freedom and tolerance, represent a valid contribution not only in terms of social assessment. They also compound a first layer for policies and strategies to create open societies and reinforce the institutional set up and rule of law. Albania, among these countries, represents a very unique case of variation in attitudes and relation toward religion along history. But a strong tolerant component characterizes the overall perception and behavior toward religious diversity. A historic, politic and social analysis of the Albanian case of religious tolerance and co-existence, necessary to understand the real western inspiration of the country and its democracy’s future, is the biggest contribution of this paper.

Opis:
The aim of the work was to analyze the changes in the population of Sus scrofa L. in the selected voivodeships in Poland in the years 2000-2011 and to determine their direction, with consideration of hunting and level of utilization. The data for analysis were obtained from Research Station of the Polish Hunting Association (PZŁ) in Czempiń. There was found the increase in population of wild boar in hunting season 2011/2012 vs. 2000/2011, including the highest one in the Świętokrzyskie Province (256%) and Małopolska Province (264%) with the simultaneous high rise in hunting (250% and 413%, respectively). The concentration of wild boar population in 6 examined voivodeships, irrespectively of basic size of the population (level of population in season 2000/2001 in the voivodeships from group I (>10 thousand heads) and group II (<1.5 thousand heads) was increased. A moderate level of population utilization occurred to be insufficient what caused a constant progression of the population number in the studies voivodeships in the years 2000-2011.

Celem pracy była analiza zmian populacji dzika europejskiego w wybranych województwach w Polsce w latach 2000-2011 oraz określenie ich kierunku z uwzględnieniem pozyskania łowieckiego i poziomu eksploatacji. Dane do analizy udostępniła Stacja Badawcza PZŁ w Czempiniu. Stwierdzono wzrost populacji dzika w sezonie łowieckim 2011/2012 vs. 2000/2001, w tym największy w województwach świętokrzyskim (256%) i małopolskim (264%), przy równocześnie znacznym wzroście pozyskania łowieckiego (250 i 413%). Zagęszczenie populacji dzika wzrosło w sześciu badanych województwach, niezależnie od bazowej wielkości populacji (liczebność populacji w sezonie 2000/2001 w województwach z grupy I (>10 tys. szt.) i grupy II (<1,5 tys. szt.). Umiarkowany poziom eksploatacji populacji okazał się być niewystarczający, co spowodowało stałą progresję liczebności populacji w badanych województwach w latach 2000-2011.

Opis:
The wild-harvested fruit of Vaccinium oxycoccos (European cranberry) is used medicinally in many European and North American countries; the plant, however, is seldom cultivated. In order to optimize the collection strategy and improve the horticulturally important characters of V. oxycoccos clones, comprehensive investigations of the species are necessary. In the present study we investigated the phenological, morphological and genetic diversity of 29 clones originating from two wild populations growing in two strictly protected Lithuanian reserves, Čepkeliai and Žuvintas. During an ex situ collection at Kaunas Botanical Garden, we observed great phenological variation between the collected V. oxycoccos clones. The following morphological traits most clearly distinguished our study clones: leaf size, berry shape, berry size and fruit colour at full maturity. The genetic variation of V. oxycoccos clones from the two populations was assessed using RAPD and SSR. RAPD analysis conducted with 9 primers resulted in 146 polymorphic loci for the total sample, and SSR analysis with 5 primers revealed 29 alleles for the total sample. A greater degree of polymorphism was demonstrated for the Čepkeliai population than for the Žuvintas population. The study allowed the selection of several clones having promising morphological traits for further testing in the field.
